detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

In the prior art, a mobile terminal usually only includes a single cell, when a large charging current is used. When charging the single cell, the heating phenomenon of the mobile terminal is very serious. In order to ensure the charging speed of the mobile terminal and alleviate the heating phenomenon of the mobile terminal during the charging process, the embodiment of the present invention remodels the battery structure in the mobile terminal, and introduces a plurality of electric cells connected in series, and the multi-section electric power is The core is directly charged. The embodiment of the present invention will be described in detail below with reference to FIG.

FIG. 1 is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal 10 of FIG. 1 includes: a charging interface 11; a first charging circuit 12, the first charging circuit 12 is connected to the charging interface 11, receives the output voltage and output current of the adapter through the charging interface 11, and outputs the output voltage and output of the adapter. The current is directly applied to both ends of the multi-section cells 13 connected in series in the mobile terminal, and the multi-cell cells 13 are directly charged.

In the prior art, the output voltage and the output current of the adapter are not directly loaded at the two ends of the cell, but the conversion voltage and the output current of the adapter are first converted through some conversion circuit, and then the converted voltage and current are loaded. Charge the battery cells to both ends of the battery. For example, the output voltage of the adapter is generally 5V. After the mobile terminal receives the 5V output voltage of the adapter, it will first use the Buck circuit to perform the step-down conversion, or use the Boost circuit to perform the step-up conversion, and then load the converted voltage into the power. Both ends of the core.

The use of the conversion circuit causes the heat generation of the mobile terminal to be severe, and the use of the conversion circuit also causes loss of power output by the adapter. In order to solve the heat generation problem caused by the conversion circuit and reduce the loss of the electric energy, the embodiment of the present invention charges the multi-section battery 13 in a direct charge manner through the first charging circuit 12.

Specifically, the direct charging may mean that the output voltage and the output current of the adapter are directly loaded (or directly guided) to both ends of the multi-cell 13 to charge the multi-cell 13 without the conversion of the converter to the adapter. The current or output voltage is transformed to avoid energy loss due to the conversion process. In the process of charging using the first charging circuit 12, in order to be able to adjust the charging voltage or charging current on the first charging circuit 12, the adapter can be designed as a smart adapter, and the charging voltage or charging current conversion circuit can be transferred to Inside the adapter, the adapter completes the conversion of the charging voltage or the charging current, which reduces the burden on the mobile terminal and simplifies the implementation of the mobile terminal.

The direct charging scheme can reduce the heat generation of the mobile terminal to a certain extent. However, when the output current of the adapter is too large, if the output current of the adapter reaches 5A-10A, the heating phenomenon of the mobile terminal will still be serious, which may occur. Security risks. In order to ensure the charging speed and further alleviate the heating phenomenon of the mobile terminal, the embodiment of the present invention further remodels the battery structure inside the mobile terminal, and introduces a plurality of cells connected in series, compared with the single cell solution. To reach For the same charging speed, the charging current required for the multi-cell is 1/N of the charging current required for a single cell (N is the number of cells connected in series in the mobile terminal), in other words, in the guarantee Under the premise of the same charging speed, the embodiment of the invention can greatly reduce the magnitude of the charging current, thereby further reducing the heat generation of the mobile terminal during the charging process.

For example, for a single-cell battery of 3000 mAh, to achieve a charging rate of 3 C, a charging current of 9 A is required. In order to achieve the same charging speed and reduce the heat generation of the mobile terminal during the charging process, two sections of 1500 mAH can be used. The cells are connected in series to replace the single-cell battery of 3000mAh. In this way, only a charging current of 4.5A is required to achieve a charging rate of 3C, and a charging current of 4.5A is caused by a charging current of 9A. The heat is significantly lower.

It should be noted that, since the first charging circuit 12 charges the multi-cell 13 in the direct charging mode, the output voltage of the adapter received by the first charging circuit 12 needs to be greater than the total voltage of the multi-cell 13; in general, The operating voltage of a single cell is between 3.0V and 4.35V. Taking the dual cell series as an example, the output voltage of the adapter can be set to be greater than or equal to 10V.

It should be noted that the type of the charging interface 11 is not specifically limited in the embodiment of the present invention. For example, it may be a Universal Serial Bus (USB) interface or a TYPE-C interface. The USB interface can be either a normal USB interface or a micro USB interface. The first charging circuit 12 can charge the multi-cell 13 through a power line in the USB interface, wherein the power line in the USB interface can be a VBus line and/or a ground line in the USB interface.

The type of the mobile terminal is not specifically limited in the embodiment of the present invention, and may be, for example, a mobile phone or a pad.

The multi-cell 13 in the embodiment of the present invention may be a battery with the same specifications or similar parameters, and the batteries with the same or similar specifications are convenient for unified management, and the batteries with the same specifications or similar parameters can be improved. The overall performance and service life of the core 13.

It should be understood that the multi-section cells 13 connected in series can divide the output voltage of the adapter.

At present, a mobile terminal (or a device in a mobile terminal or a chip in a mobile terminal) is powered by a single battery. In the embodiment of the present invention, a multi-cell battery is connected in series, and the total voltage of the multi-cell is high. Not suitable for direct use to power a mobile terminal (or a device within a mobile terminal, or a chip within a mobile terminal). In order to solve this problem, a feasible implementation manner is to adjust the working voltage of the mobile terminal (or the device in the mobile terminal or the chip in the mobile terminal) to support multi-cell power supply, but this implementation manner The changes to the mobile terminal are large and the cost is high. An implementation manner according to an embodiment of the present invention will be described in detail below with reference to FIG. 2 and FIG. 3 to solve the problem of how to supply power under the multi-cell battery scheme.

Optionally, in some embodiments, as shown in FIG. 2, the mobile terminal 10 may further include: a buck circuit 21, and an input end of the buck circuit 21 is connected to both ends of the multi-section cell 13 for total voltage power-saving core 13 into a first voltage V 1, wherein a≤V 1 ≤b, a represents (chips within the device or within the mobile terminal 10 or mobile terminal 10) of the mobile terminal 10 the minimum operating voltage, b represents the maximum operating voltage of the mobile terminal 10 (or the device in the mobile terminal 10, or the chip in the mobile terminal 10); the power supply circuit 22 is connected to the output of the step-down circuit 21, and supplies power to the mobile terminal 10 based on the first voltage. .

The embodiment of the present invention introduces the step-down circuit 21 on the basis of the embodiment described in FIG. 1. When the mobile terminal is in the working state, the total voltage of the multi-section battery 13 is first stepped down by the step-down circuit 31 to obtain the first The voltage, because the first voltage is between the minimum operating voltage and the maximum operating voltage of the mobile terminal 10, can be directly used to power the mobile terminal, and solves the problem of how to supply power under the multi-cell battery scheme.

It should be noted that the total voltage of the multi-cell 13 is changed according to the change of the electric quantity of the multi-cell 13 . Therefore, the total voltage of the multi-cell 13 above may refer to the multi-cell 13 Current total voltage. For example, the operating voltage of a single cell can be between 3.0V and 4.35V. Assuming that the multi-cell contains 2 cells and the current voltage of both cells is 3.5V, the multi-section above The total voltage of the core 13 is 7V.

Taking the operating voltage range of a single cell as 3.0V-4.35V as an example, a=3.0V and b=4.35V. In order to ensure the normal supply voltage of the device in the mobile terminal, the step-down circuit 21 can The total voltage of the multi-cell 13 is dropped to any value in the range of 3.0V - 4.35V. The step-down circuit 21 can be implemented in various manners, for example, a buck circuit, a charge pump, or the like can be used to implement step-down.

It should be noted that the buck circuit 21 can be a charge pump, and the total voltage of the multi-cell 13 can be directly reduced to 1/N of the current total voltage by the charge pump, where N represents the multi-cell 13 The number of batteries. The traditional Buck circuit includes switching transistors and inductors, and the losses of the inductors are relatively large. Therefore, the buck circuit will cause the power loss of the multi-cell 13 to be relatively large. Compared with the Buck circuit, the charge pump is mainly used. The switch tube and the capacitor are stepped down, and the capacitor basically does not consume extra energy. Therefore, the use of the charge pump can reduce the circuit loss caused by the step-down process. Specifically, the switching tube inside the charge pump controls the charging and discharging of the capacitor in a manner such that the input voltage is reduced by a factor (the factor selected in the embodiment of the present invention is 1/N), thereby obtaining the required voltage.

Optionally, in other embodiments, as shown in FIG. 3a, the mobile terminal 10 may further include: a power supply circuit 32, an input end of the power supply circuit 32, and two ends of any single cell in the multi-section battery 13 Connected, the power supply circuit 32 supplies power to the devices within the mobile terminal 10 based on the voltage of the single cell 13.

It should be understood that the voltage after the step-down circuit is stepped down may cause ripple, thereby affecting the power quality of the mobile terminal. The embodiment of the present invention directly draws power from both ends of a single cell in the multi-section cell. The voltage is used to supply power to the device in the mobile terminal. Since the voltage output from the cell is relatively stable, the embodiment of the present invention can maintain the power quality of the mobile terminal while solving the problem of how to supply power under the multi-cell solution.

Further, on the basis of the embodiment of FIG. 3a, as shown in FIG. 3b, the mobile terminal 10 may further include an equalization circuit 33 connected to the multi-section battery 13 for balancing each of the plurality of cells 13. The voltage between the cells.

After adopting the power supply mode shown in FIG. 3a, the battery core (hereinafter referred to as the main battery core, the remaining battery core is called the slave battery core) for powering the devices in the mobile terminal will continue to consume power, resulting in the main battery and the slave battery. The voltage imbalance between the two (or the voltage is inconsistent), the voltage imbalance between the multi-cell 13 will reduce the overall performance of the multi-cell 13 and affect the service life of the multi-cell 13 and, in addition, the multi-cell 13 The voltage imbalance between the two can cause the multi-section battery 13 to be difficult to manage uniformly. Therefore, the embodiment of the present invention introduces the equalization circuit 33 to balance the voltage between the cells in the multi-section battery 13 to improve the multi-section. The overall performance of the battery core 13 facilitates unified management of the multi-section batteries 13.

The equalization circuit 33 is implemented in many ways. For example, the load can be connected from both ends of the cell, and the amount of electricity from the cell is consumed to be consistent with the amount of the main cell, so that the voltage of the main cell and the cell are maintained. Consistent. Alternatively, it is possible to charge the cell from the cell until the voltage of the main cell and the cell coincide.

As the output power of the adapter becomes larger, when the adapter charges the battery cells in the mobile terminal, it is easy to cause lithium deposition of the battery core, thereby reducing the service life of the battery core.

In order to improve the reliability and safety of the battery, in some embodiments, the adapter output pulsating direct current (or unidirectional pulsating output current, or pulsating waveform current, or 馒 head wave current) may be controlled, due to the first The charging circuit 12 adopts a direct charging mode, and the pulsating direct current outputted by the adapter can be directly loaded to both ends of the multi-section battery 13. As shown in FIG. 4, the current of the pulsating direct current is periodically changed, and the pulsating direct current can be compared with the constant current. Reduce the lithium deposition phenomenon of the lithium battery and improve the service life of the battery. In addition, the pulsating direct current can reduce the probability and intensity of the arcing of the contacts of the charging interface compared to the constant current, and improve the life of the charging interface.

There are various ways to set the output current of the adapter to pulsating DC. For example, the secondary filter circuit in the adapter can be removed, and the output current of the secondary rectifier circuit (the output current of the rectifier circuit is pulsating DC) can be directly used as an adapter. Output current.

Similarly, in some embodiments, the output voltage of the adapter received by the first charging circuit 12 is the voltage of the pulsating waveform, and the voltage of the pulsating waveform may also be referred to as a unidirectional pulsating output voltage, or a head wave voltage.

Optionally, in some embodiments, the output current of the adapter received by the first charging circuit 12 may also be an alternating current (for example, the adapter does not need to perform rectification and filtering, and the utility power is directly stepped down and output), and the alternating current can also be Reduce the lithium deposition phenomenon of the lithium battery and improve the service life of the battery.

Optionally, in some embodiments, the charging mode of the first charging circuit 12 is a constant current mode. It should be understood that the constant current mode means that the charging current is kept constant for a period of time, and does not mean that the charging current is always kept constant. In practice, in the constant current mode, the first charging circuit 12 can be adjusted in real time according to the current voltage of the plurality of cells. The constant current mode corresponds to the charging current to achieve a piecewise constant current. Further, if the output current of the adapter received by the first charging circuit 12 is pulsating direct current, the charging mode of the first charging circuit 12 is a constant current mode, which may mean that the peak value of the pulsating direct current or the average value of the pulsating direct current remains constant for a period of time. If the output current of the adapter received by the first charging circuit 12 is alternating current, the charging mode of the first charging circuit 12 is a constant current mode, which may mean that the peak or average value of the forward current of the alternating current remains constant for a period of time.

Optionally, in some embodiments, as shown in FIG. 5, the multi-cell batteries 13 may be collectively packaged in one battery 51. Further, the battery 51 may further include a battery protection board 52, which may be through the battery protection board 52. Realize overvoltage and overcurrent protection, battery balance management, and power management.

Optionally, in some embodiments, as shown in FIG. 6, the mobile terminal 10 may further include: a second charging circuit 61, the second charging circuit 61 includes a boosting circuit 62, and the two ends of the boosting circuit 62 are respectively charged The interface 11 is connected to the multi-cell 13, and the boosting circuit 62 receives the output voltage of the adapter through the charging interface 11, boosts the output voltage of the adapter to the second voltage, and loads the second voltage into the two of the multi-cell 13 And charging the multi-cell, wherein the output voltage of the adapter received by the second charging circuit 61 is less than the total voltage of the multi-cell, and the second voltage is greater than the total voltage of the multi-cell 13.

As can be seen from the above, the first charging circuit 12 directly charges the multi-cell 13 , which requires the output voltage of the adapter to be higher than the total voltage of the multi-cell 13 , for example, a scheme for connecting two cells in series In other words, assuming that the current voltage of each cell is 4V, when the first charging circuit 12 is used to charge the two cells, the output voltage of the adapter is required to be at least greater than 8V, but the common adaptation The output voltage of the device is generally 5V, and the normal adapter cannot charge the multi-cell 13 through the first charging circuit 12. In order to be compatible with the charging mode provided by the conventional adapter, the embodiment of the present invention introduces a second charging circuit 61, the second charging. The circuit 61 includes a boosting circuit that can raise the output voltage of the adapter to a second voltage to be greater than the total voltage of the multi-cell 13 to solve the multi-cell 13 that the common adapter cannot be connected in series with each other. Charging problem.

It should be noted that, in the embodiment of the present invention, the voltage value of the output voltage of the adapter received by the second charging circuit 61 is not specifically limited, as long as the output voltage of the adapter is lower than the total voltage of the multi-cell 13 After the charging circuit 61 boosts the voltage, the multi-cell 13 is charged.

It should be noted that the specific form of the booster circuit is not limited in the embodiment of the present invention. For example, a boost boost circuit may be used, and a charge pump may be used for boosting. Optionally, in some embodiments, the second charging circuit 61 can adopt a conventional charging circuit design manner, that is, a charging management chip is disposed between the charging interface and the battery core, and the charging management chip can perform constant charging on the charging process. Constant current control, and adjusting the output voltage of the adapter according to actual needs, such as step-up or step-down, the embodiment of the present invention can utilize the boost function of the charging management chip to boost the output voltage of the adapter to be higher than the multi-section power. The second voltage of the total voltage of the core 13. It should be understood that the switching between the first charging circuit 12 and the second charging circuit 61 can be implemented by a switch or a control unit, for example, a control unit is provided inside the mobile terminal, and the control unit can be based on actual needs (such as the type of the adapter). The first charging circuit 12 and the second charging circuit 61 are flexibly switched.

Optionally, in some embodiments, the charging mode corresponding to the first charging circuit 12 may be referred to as a fast charging mode, the charging mode corresponding to the second charging circuit 61 may be referred to as a normal charging mode, and the charging speed of the fast charging mode is greater than a normal charging mode. The charging speed of the charging mode, such as the charging current of the fast charging mode, is greater than the charging current of the normal charging mode. For example, the normal charging mode can be understood as a charging mode with a rated output voltage of 5V and a rated output current of 2.5A or less; the fast charging mode can be understood as a high current charging mode, and the charging current of the fast charging mode can be higher than 2.5A. For example, it can reach 5-10A, and the fast charging mode uses the direct charging mode, that is, directly loads the adapter's output voltage and output current to both ends of the cell.

The communication process between the mobile terminal and the adapter will be described in more detail below with reference to specific examples. It should be noted that the example of FIG. 8 is only intended to assist those skilled in the art to understand the embodiments of the present invention, and the embodiments of the present invention are not limited to the specific numerical values or specific examples illustrated. A person skilled in the art will be able to make various modifications or changes in the embodiments according to the example of FIG. 8. The modifications or variations are also within the scope of the embodiments of the present invention.

As shown in Figure 8, the fast charge process can consist of five phases:

Phase 1:

After the control unit 71 is connected to the power supply device, the mobile terminal can detect the type of the power supply device through the data lines D+, D-. When the power supply device is detected as an adapter, the current absorbed by the mobile terminal can be greater than a preset current threshold. I2 (for example, it can be 1A). When the adapter detects that the output current of the adapter is greater than or equal to I2 within a preset duration (eg, may be continuous T1 time), the adapter may consider that the type identification of the power supply device by the mobile terminal has been completed, and the adapter opens the adapter and control unit 71. In the handshake communication, an instruction 1 (corresponding to the first instruction described above) is sent to the control unit 71 to inquire whether the control unit 71 turns on the fast charging mode (or referred to as a flash charging mode).

When the adapter receives the reply command of the instruction 1 sent by the control unit 71, and the reply command of the command 1 indicates that the control unit 71 does not agree to turn on the fast charge mode, the adapter detects its own output current again, when the output current of the adapter is preset. When the continuous duration (for example, may be continuous T1 time) is still greater than or equal to I2, the command 1 is again sent to the control unit 71, inquiring whether the control unit 71 turns on the fast charge mode. The adapter repeats the above steps of Phase 1 until the control unit 71 agrees to turn on the fast charge mode, or the output current of the adapter no longer satisfies the condition of greater than or equal to I2.

When the control unit 71 agrees to turn on the fast charging mode, the fast charging process is turned on, and the fast charging communication process enters the second stage.

Stage 2:

The output voltage of the adapter may include a plurality of gear positions, and the adapter sends an instruction 2 to the control unit 71. (corresponding to the second instruction described above) to ask whether the current voltage output by the adapter is suitable as the charging voltage of the fast charging mode (or, the instruction 2 inquires whether the current voltage output by the adapter matches the current voltage of the multi-cell 13).

The control unit 71 sends a reply command of the instruction 2 to the adapter to indicate that the current voltage output by the adapter is suitable, high or low. If the reply command of the instruction 2 indicates that the current voltage of the adapter output is high or low, the adapter can The current voltage of the output is adjusted by one gear position, and the command 2 is sent again to the control unit 71, and it is re-queried whether the current voltage output by the adapter is suitable as the charging voltage of the fast charging mode. The above steps of phase 2 are repeated until control unit 71 determines that the current voltage output by the adapter is suitable as the charging voltage for the fast charging mode, entering phase 3.

Stage 3:

The adapter sends an instruction 3 (corresponding to the third instruction described above) to the control unit 71, inquiring about the maximum charging current currently supported by the control unit 71, and the control unit 71 sends a reply command of the instruction 3 to the adapter to indicate the maximum charging current currently supported by the mobile terminal. And enter the fourth stage.

Stage 4:

The adapter determines the charging current of the fast charging mode according to the maximum charging current currently supported by the mobile terminal, and then enters phase 5, that is, the constant current phase.

Stage 5:

After entering the constant current phase, the adapter sends an instruction 4 (corresponding to the fourth instruction described above) to the control unit 71 every time interval, inquiring about the current voltage of the multi-cell 13, and the control unit 71 can send a reply command of the instruction 4 to the adapter. In order to feed back the current voltage of the multi-cell 13 , the adapter can judge whether the contact of the charging interface is good according to the current voltage of the multi-cell 13 and whether it is necessary to reduce the output current of the adapter. When the adapter determines that the charging interface is in poor contact, the command 5 (corresponding to the fifth command described above) may be sent to the control unit 71, and then reset to re-enter the phase 1.

Optionally, in some embodiments, in the phase 1, when the control unit 71 sends the reply instruction of the instruction 1, the reply command of the instruction 1 may carry the data (or information) of the path impedance of the mobile terminal, and the mobile terminal The path impedance data can be used to determine if the contact of the charging interface is good at stage 5.

Optionally, in some embodiments, in phase 2, the time elapsed from the mobile terminal agreeing to activate the fast charging mode until the adapter adjusts the output voltage to the appropriate voltage may be controlled within a certain range if the time exceeds a predetermined time Range, the control unit 71 can determine that the fast charge has been communicated The process is abnormal and reset to re-enter Phase 1.

Optionally, in some embodiments, in phase 2, when the current voltage output by the adapter is higher than the current voltage of the multi-cell 13 by ΔV (ΔV may be set to 200-500 mV), the control unit 71 sends the adapter to the adapter. Command 2's reply command to indicate that the current voltage output by the adapter is appropriate.

Optionally, in some embodiments, in stage 4, the adjustment speed of the output current of the adapter may be controlled within a certain range, so that the charging process abnormality of the first charging circuit 12 due to the excessive adjustment speed may be avoided.

Alternatively, in some embodiments, in stage 5, the magnitude of the change in the output current of the adapter can be controlled to within 5%.

Optionally, in some embodiments, in stage 5, the adapter can monitor the path impedance of the first charging circuit 12 in real time. Specifically, the adapter can be based on the output voltage of the adapter, the output current, and the multi-section power fed back by the control unit 71. The current voltage of the core 13 monitors the path impedance of the first charging circuit 12. When the path impedance of the first charging circuit 12 > the path impedance of the mobile terminal + the impedance of the charging cable, the charging interface may be considered to be in poor contact, and charging using the first charging circuit 12 may be stopped.

Optionally, in some embodiments, after the fast charging mode is turned on, the communication time interval between the adapter and the control unit 71 can be controlled within a certain range to avoid the communication interval being too short to cause the fast charging communication process to be abnormal.

Alternatively, in some embodiments, the stop of the fast charge process (or the stop of the fast charge mode) can be divided into two types: a recoverable stop and an unrecoverable stop:

For example, when it is detected that the multi-cell 13 is full or the charging interface is in poor contact, the fast charging process is stopped, the fast charging communication process is reset, and the phase 1 is re-entered, the mobile terminal does not agree to turn on the fast charging mode, and the fast charging communication process does not enter the stage. 2. The stop of the fast charge process in this case can be considered as an unrecoverable stop.

For another example, when a communication abnormality occurs between the control unit 71 and the adapter, the fast charging process is stopped, the fast charging communication process is reset, and the phase 1 is re-entered. After the requirement of the phase 1 is satisfied, the control unit 71 agrees to turn on the fast charging mode to recover. In the fast charge process, the stop of the fast charge process in this case can be considered as a recoverable stop.

For another example, when the control unit 71 detects that an abnormality occurs in one of the plurality of cells 13 , the fast charging process is stopped, the fast charging communication process is reset, and the phase 1 is re-entered, and the control unit 71 does not agree to turn on the fast charging mode. When the multi-cell 13 is restored to normal and the requirements of the phase 1 are met, the control unit 71 agrees to turn on the fast charging mode, and the stop of the fast charging process in this case can be regarded as Recoverable stop.

It should be noted that the communication step or operation shown in FIG. 8 is only an example. For example, in the phase 1, after the mobile terminal is connected to the adapter, the handshake communication between the control unit 71 and the adapter may also be The control unit 71 initiates, that is, the control unit 71 sends an instruction 1 to inquire whether the adapter turns on the fast charging mode, and when the control unit 71 receives the reply command from the adapter to instruct the adapter to agree to turn on the fast charging mode, the first charging circuit 12 is a multi-cell battery. 13 charging.

It should be noted that the communication steps or operations shown above for FIG. 8 are merely examples. For example, after phase 5, a constant voltage charging phase may also be included, ie, in phase 5, the control unit 71 may be to the adapter. The current voltage of the multi-cell 13 is fed back. When the current voltage of the multi-cell 13 reaches the constant voltage charging voltage threshold, the charging phase is switched from the constant current phase to the constant voltage phase, and in the constant voltage phase, the charging current is gradually decreased. When the current drops to a certain threshold, charging stops, indicating that the multi-cell 13 has been fully charged.
